ELEVAIOR CYLINDER- ALINING DEVICE.

SPECIFICATION forming part of Letters Patent No. 617,357, dated January10, 1899.

Application filed October 8, 1897. Serial No. 654,524. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE H. REYNOLDS, a citizen of the United States,residing in Chicago, Cook county, Illinois, have invented a certain newand Improved Elevator-Cylinder- Alining Device, of which the following,taken in connection with the accompanying drawings, is a specification.

The subject-matter of this specification was originally a part of anapplication filed by me April 30, 1897, Serial No. 634,547.

Myinvention has particular relation to that class of elevators in whicha weighted ram or plunger is used to raise the car, the car beinglowered by hydraulic pressure acting upon it so as to raise said ram orplunger.

In elevators of the above-mentioned class difficulty has beenexperienced in keeping the cylinder in perfect alinement. In highbuildings the plunger used is very long and must of course operatewithout rubbing or friction upon the inside surface of the cylinder. Bythe improvement which I will now describe in connection with theaccompanying drawings I am enabled to readily and reliably secure suchaccurate alinement of the cylinder with the greatest degree of nicety.

Figure 1 is a partial elevation of such an elevator-cylinder as I haveabove referred to with my improvement applied thereto. Fig. 2 is anenlarged view showing more clearly the application of the improvement tothe cylinder at one of the floor-beams, and Fig. 3 is a plan view andsection of the construction shown in Fig. 2.

The cylinder at is provided at each of the floor-beams 5 with a pair ofhook-bolts 6, a strap 7, and a saddle-block 8, in which are a couple ofadj usting-screws 9. On the ends of the hook-bolts 6 are adjusting-nuts10. If it be desired to move the cylinder in or out from the floor-beam5 in order tobring it into alinement,this may be readily accomplished bytightening or loosening the nuts 10 and setting the screws 9in properposition, and if it be desired to move the cylinder parallel with theI-beam this is readily done by loos ening the nuts 10 and sliding thehook-bolts 6 along the floor-beam in a manner which will be readilyunderstood from the drawings without a more detailed explanation andthen tightening the nuts 10 to hold the strap 7 firmly in place. I

' By the means described the cylinder may be readily adjusted and alinedeither inward between the cylinder and beam, and a plurality ofset-screws in said saddle-block arranged to alter the relative positionof the beam and cylinder,substantially as described.

GEORGE H. REYNOLDS.
